Creativity - Free will, action points, and a lot of super stuff.
Reflexes - Saves and initiative and some abilities.
Aptitude - Skill points.
Vitality - Constitution and endurance.
Influence - Charisma and the 'luck' stat; it affects all others slightly.
Nimbleness - Actions/turn and avoiding danger you are aware of.
Grit - Fortitude and will; both saves or tests or required for use of some abilities.
Strength - Lifting, speed, and base melee.

No ability can go higher than 10 max or 1 minimum, if you're human - unless you have some external benefit/negative such as being on drugs or physically/mentally disabled/insane. Also, the stats are meant to define the core character - each stat directly constributes to an actual thing the character does in some way, whether it's casting a spell, or performing a more specific ability or combat technique, etc., etc. In this way, the set of skills a character picks could be his 'class'.

EDIT: Sorry if that's too non-open for interpretation. I got a little ahead is all. -_-

This seems too much like a DnD centric interpretation for my liking.
Maybe you just used it for clarification, though my fear is that in equal parts it stops new ideas from occuring.
Also, I think deciding on what each stat does will happen in later posts, not a clarification.
(A clarification would -in my mind- happen after a rule is made, though worded possibly ambiguously.)
